Odd Lighting Effect

There is an odd lighting glitch that i would like to know what this is and how to fix it

I’m using the latest version of the HDRP and Unity 2020

Ah shoot here

Seems like you’re using latest 9.x/10.x HDRP version with screen space global illumination - it’s prone for those large blocky artifacts (going to “Custom” settings in global illumination settings and maxing out “Filter radius” to 8 may help smooth those). Also, check volumetric lighting on this sun ? - if disabling volumetrics removes those artifacts it was not GI problem, it’s volumetric fog settings (enable advanced fog settings using gear icon on it’s right top and enable filtering/more samples).

Can you disable volumetrics and try again? I am nore sure we are looking at something ray-tracing related here.
